Sludge Recirculation Rate given MLSS and SVI Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sludge Recirculation Rate given MLSS = Sewage Discharge*(MLSS/(((10^6)/Sludge Volume Index given Sewage Discharge)-MLSS))
Q_r' = Q_s*(X/(((10^6)/SVI_s)-X))
This formula uses 4 Variables

Variables Used

Sludge Recirculation Rate given MLSS - (Measured in Cubic Meter per Second) - Sludge Recirculation Rate given MLSS is the rate at which sludge is returned from the secondary clarifier to the aeration tank in a wastewater treatment plant.
Sewage Discharge - (Measured in Cubic Meter per Second) - Sewage discharge is the flow rate of sewage when it is being discharged in the river.
MLSS - (Measured in Kilogram per Cubic Meter) - MLSS is the sum of volatile suspended solids (organics) and fixed suspended solids (inorganics).
Sludge Volume Index given Sewage Discharge - (Measured in Cubic Meter per Kilogram) - Sludge Volume Index given Sewage Discharge is the ratio of volume to MLSS.

STEP 1: Convert Input(s) to Base Unit

Sewage Discharge: 10 Cubic Meter per Second --> 10 Cubic Meter per Second No Conversion Required
MLSS: 1200 Milligram per Liter --> 1.2 Kilogram per Cubic Meter (Check conversion here)
Sludge Volume Index given Sewage Discharge: 0.5 Liter per Gram --> 0.5 Cubic Meter per Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q_r' = Q_s*(X/(((10^6)/SVI_s)-X)) --> 10*(1.2/(((10^6)/0.5)-1.2))

Evaluating ... ...

Q_r' = 6.00000360000216E-06

STEP 3: Convert Result to Output's Unit

6.00000360000216E-06 Cubic Meter per Second -->0.518400311040187 Cubic Meter per Day (Check conversion here)

FINAL ANSWER

0.518400311040187 ≈ 0.5184 Cubic Meter per Day <-- Sludge Recirculation Rate given MLSS
